* include/grub/powerpc/ieee1275/ieee1275.h: Move ... * include/grub/ieee1275/ieee1275.h: ... to here. All users updated. Move `abort', `grub_reboot', and `grub_halt' prototypes ... * include/grub/powerpc/ieee1275/kernel.h: ... to here. * commands/ieee1275/halt.c: Include <grub/machine/kernel.h> instead of <grub/machine/ieee1275.h>. * commands/ieee1275/reboot.c: Likewise. * boot/powerpc/ieee1275/ieee1275.c: Move ... * kern/ieee1275.c: ... to here. All users updated. Change all parameter structs to use new type `grub_ieee1275_cell_t'. * term/powerpc/ieee1275/ofconsole.c: Move ... * term/ieee1275/ofconsole.c: ... to here. All users updated. * disk/powerpc/ieee1275/ofdisk.c: Move ... * disk/ieee1275/ofdisk.c: ... to here. All users updated. * boot/powerpc/ieee1275/cmain.c: Change `grub_ieee1275_entry_fn' type to return int. * include/grub/i386/pc/console.h: Move to include/grub/console.h. Remove unused prototypes. All users updated. * include/grub/powerpc/ieee1275/console.h: Removed. * include/grub/powerpc/ieee1275/ieee1275.h: Define `grub_ieee1275_cell_t'. * kern/powerpc/ieee1275/openfw.c: Include <grub/machine/kernel.h>. Cast comparisons with -1 to the correct type. * loader/powerpc/ieee1275/linux.c (kernel_entry_t): Change parameter type to match `grub_ieee1275_entry_fn'.
